From: Tom Zanussi <tom.zanu...@linux.intel.com> Add a feature allowing the enablement of LTO (Link-Time Optimization) for the Linux kernel. To enable LTO for the kernel, add (for example):
KERNEL_FEATURES_append_galileo += " features/lto.scc" Note that this feature requires special toolchain support (HJ Lu's Linux binutils and gcc >= 4.9).
